<p>The disk (1) has an activating unit (21) i.e. actuation body, for activating a blocking device (6), where the activating unit is elastically deformed and associated in a sliding way to a lock (20). The blocking device blocks blades in a position. A holding unit (33) holds the activating unit when the holding unit passes from an initial free position to a locked final position. The lock cooperates spontaneously by its elasticity with the holding unit in the locked final position for which the blocking device is in an active state with the lock engaged in the housing.</p> |
